McCall was sacked as manager on Sunday, giving Sellars and Trueman little time to prepare for Tuesday’s 1-1 draw at Crawley. They will take charge again for Saturday’s League Two visit of Cambridge United.
The aim is to have a new man for Tuesday’s trip to Grimsby Town, but Sellars say the pair are happy to continue working together on a “best idea wins” basis for as long as is needed.
“I believe we’ve got until Saturday,” he said. “The club have been looking at people but until that happens we’ve just got to do our job and help the team.
“When that call that they’ve got the manager comes we’re happy to pass the reins on. I’m sure it will be the right person.”
As it will be for the new manager – Paul Hurst, John McGreal and David Flitcroft have been linked – coaching time has been tight.
“You have to be clever about it, whether it’s more analysis or work on the pitch which is slower, less demanding and less intense,” explained Sellars. “We need laser vision on what these players need to get results. That’s the skill of a coach.
“Mark and I share the load so we’re both fresh. We work really well together so it comes quite naturally. We have similar values and trust each other thoroughly.
“It’s best idea wins. It’s being humble as well as having beliefs so we have healthy debates.”
Callum Cooke has recovered from a dead leg but Leeds United loanee Bryce Hosannah is unavailable, with no timescale on his return from injury.
The Bantams will make late calls on Gareth Evans, Billy Clark and Kurtis Guthrie.
